"You're such a rude and self-centered asshole you know that ? I can't believe somebody as twisted as you actually exist." "Damn, what a poor description of my whole being you are making princess. You almost hurt my feelings here. I am everything but rude." This could have been the boring story of a new girl entering college, finding love, getting married and having a calm and peaceful life. Too bad (or not ?) Lisa isn't driven by any objective of the kind.

Lisa Manoban, a foreign exchange student in South Korea, finds her world, everything she knows and believes tested to their limits, along with her sanity when one day she enters a hidden room on her campus and walks into an American high school in 1964. There, she meets a student called Jennie Kim who makes Lisa's life even more difficult. Is Lisa crazy or has she really found a door that allows her to travel through time and across the world?
